Interstellar Highway System

  • Published on: 03 April 2019
  • Could advanced civilizations be using a network of black holes for interstellar travel? In our last video, the "halo drive" was discussed covering the basic physics of how this new system could potentially enable interstellar flight. Here, we go much deeper on the halo drive concept, answering many of the questions which have been raised, and going further by considering the possibilities of a galactic wide network of such systems.

    This video is based on research conducted at the Cool Worlds Lab at Columbia University. You can now support our research program directly here: https://www.coolworldslab.com/support

    To stabilise the spacecraft, couldn't you just force it into a constant freefall into the black hole, that you counterbalance with the Halo Drive? Using something like an anchor on a long string that is much closer to the black hole.

    I honestly think you’re breaking academic ground here in a way that many others will replicate in the future. Your channel gives you the opportunity to attract public interest for your research work. I’ve seen public outreach work punished so much generally, but yours is so much around your own published research so it’s unarguable to your peers that you’re putting in the expected effort to do research and get published. And you present it in an engaging way that I know that many conventional academics would struggle with.I look forward to see where this channel goes and what academia is like in another 10 or 15 years. Not every field will translate as well to YouTube videos as cosmology and astrophysics, but I can imagine steps in this direction at least.

    Could we do this with a neutron star binary as well, if we used a well-timed pulsed laser and had the beam loop around both neutron stars to get back to the ship? If not, there should be some number of neutron stars that we could use to achieve this.

    Isn't here a chicken and egg problem here? You need the black hole for an interstellar speed boost, but first you need interstellar travel to get near enough to a black hole to fire you laser at?

    If a ball of rock can steal energy then we will one day do the same and then again and again. We just need to find a way to live through what would take generations to master, nothing is impossible in the era of humanity

    This is less of a physics question and more of a logistics question, and maybe you already answered this in your previous video...but how do we get to the black holes in order to use the Halo Drive?

    And also maintain massive amounts of energy to stop. Assuming we actually got started, we'd still have to stop.

    I feel like anytime you start off with, "first you're gonna need a blackhole..." you might as well write it off and impossible or at least improbable haha. Love your channel mate! Just found it a couple weeks ago and have been getting through all the videos. Any chance you'll look at any research into the realm of reactionless drives or ion drives?

    "Stealing" black hole energy with light propulsion systems (I guess you're calling it a halo drive) is possibly a way for us to go interstellar in a distant future. However I do not see why you would have to constrain yourself to 1g (you weigh what you weigh on earth) for a pleasant experience, as we have plenty of ways already to deal with positive and negative g-forces in racing, piloting and space traveling currently, albeit for brief moments. In formula one, correctly and safely strapped to the vessel, drivers crash at extreme G-forces over 50g and walks away like on a sunday stroll down the park. Combining G-force management with a plausible and effective propulsion system is in my eyes a "possible way to go". A constant high G would be horrible but a high G "initial kick" is not something to have too many concerns about, or do you mean that the G-force with the system would be constant? Then what G could we actually tolerate for a longer time? 2G on a normal body is possibly relatively like being very obese, so obviously not too harmful but not pleasant. Would like to see the experiment though where the beam actually comes back to the point you aim for after slinging around a black hole.Anyways fascinating scientific calculations and speculations, but anti gravity research is probably what we all would like to "crack" as weightless objects require less energy for any action and reaction to be more effective. Is it a figment of imagination or a key to negate all the gravitic forces of the universe? Who knows, it's obviously not "cracked yet", at least not in a sense of being released to the public or confirmed by science. I fully love the encouragement for everyone to think a little bit more on these things, however, not everybody is able to think about the concepts at all. WIth that said, I think it is cool to think about, dare to dream about what others fear or ridicule, too many times in history the bullies have been proven wrong!

    One thing not being considered is in order to use a halo drive, one must get TO a black hole. The nearest one is as at least a hundred light years away. So in essence, you need another near speed of light drive in order to use a near speed of light drive. This renders any halo drive useless, and any effort into considering it mute.

  • blarvinius

    Question: You say "a stationary black hole" and "Jupiter isn't moving fast enough"... But isn't everything in some orbit? Aren't all black holes moving (very fast) in some direction? So couldn't a halo drive benefit from a Doppler shift in the same direction of the trajectory of the lone black hole?

    Put yourself unto orbit around it, and use radiation from the black hole as your energy source. Electromagnetic methods also possibly, similar to how wireless charging works

    Alright. So the Mass Relays network can be real, just add black holes instead!Also I'm just so amazed by this concept, or generally by this channel.It's like... It's like what we think of Leonardo DaVinci and his inventions he couldn't create because of lack of good materials, but for our future!

    You could maybe, rather than build a civilization around a single black hole, find two spinning black holes to bounce back and forth between, presumably using a space station with a halo drive on each end. You'd have to switch all the furniture from floor to ceiling ever few years but it could be like a fun festival event

    Wonderful video! Since this vid has already discussed the "distance" problems of interstellar scale, I'm curious about chronological problems of the same scale. If building an interstellar/intergalactic world is possible, is there any ways to keep a uniform pace of time across the entire worlds?(i.e. making an interstellar caldenar) My guess is general relativity will prevent making such thing. But...there might be an unknown solution I guess lol

    To slow down cant we just fire the beam at a smaller shuttle which would reflect back the beam and not necessarily at a blackhole?

    Please describe the physics involved in the following scenario: Say you have a very massive space ship, from the front of such ship, lets suppose you built a detachable capsule of sorts that is orders of magnitude lighter than the space ship from which it came. Now lets also suppose we have a "cable" that attaches the two crafts, and for thought sake lets say this "cable" is "Infinitely strong", Now say we park our very large spaceship in such a space around a blackhole and with the capsule detaching from the ship towards the blackhole, Just how close could our capsule get to a black hole and still be able to recover from the blackholes gravity? Could we learn anything from the perspective of being in such a proximity? Could impossible experiments be lent to us in such an environment? Please expound.

    I think the spacecraft would inevitably be swallowed by the black hole,Getting close enough to slingshot around it sounds like fun but i fail to see its true power source that is syphon available Just saying ,im a crane rigger who is interested in spacecraftLiked the video,fascinating to watch

    Could you convert the incoming halo drive energy into angular momentum? In the same way a hydroelectric dam takes a steady stream of water and runs it through a dynamo to generate electricity, could the incoming halo drive beam spin a dynamo to become a source of energy rather than propulsion? (ie, the propulsion is put into turning the dynamo). Depending on how efficient the bearing was, there could be negligible momentum imparted beyond the spin (and LOTS of electricity for our black hole orbiting civilisation)
